House prices report

This document is a data science report of the kaggle house prices tutorial project. It was generated using the Shapash library.

General Information

Version : 0.7

Name : House Prices Prediction Project

Purpose : Predicting the sale price of houses

Date : 2021-10-27

Contributors : Yann Golhen, Sebastien Bidault, Thomas Bouche, Guillaume Vignal, Thibaud Real

Description : This work is a data science project that tries to predict the sale of houses based on 79 explanatory variables. It was designed inside the data science team at X. and improved since the beggining of the project in 2019. The model was put into production since February 2021.

Dataset Information

Path : https://www.kaggle.com/c/house-prices-advanced-regression-techniques/

Origin : The Assessor’s Office

Description : the sale of individual residential property in Ames, Iowa

Depth : from 2006 to 2010

Perimeter : only residential sales

Target Variable : SalePrice

Target Description : The property's sale price in dollars

---

Data Preparation

Variable Filetring : All variables that required special knowledge or previous calculations for their use were removed

Individual Filtering : only the most recent sales data on any property were kept (for houses that were sold multiple times during this period)

Missing Values : were replaced by 0

Feature Engineering : No feature was created. All features are directly taken from the kaggle dataset. Categorical features were transformed using an ordinal encoder.

Model Training

Used Algorithm : We used a RandomForestRegressor algorithm (scikit-learn) but this model could be challenged with other interesting models such as XGBRegressor, Neural Networks, ...

Parameters Choice : We did not perform any hyperparameter optimisation and chose to use n_estimators=50. Future works should be planned to perform gridsearch optimizations

Metrics : Mean Squared Error metric

Validation Strategy : We splitted our data into train (75%) and test (25%)
